ABSTRACT
The solubility of benzoic acid in water-ethanol and water-n-propanol mixtures at temperatures between (303.5 and 333.7) K has been measured by using an apparatus in our laboratory. Experiments were carried out employing different concentrations of alcohol. Addition of alcohol in water results in a large increase in acid solubility. Owing to a lack of available literature data, no results comparison could be done for systems containing n-propanol. Furthermore, the predicted results of solubility for the systems studied over a range of temperatures indicated that both modified equations tested can fairly be used to predict solid-liquid equilibrium for alcoholic aqueous solutions at several temperatures.
